To limit the duration of recording sessions to less than 8 minutes, as suggested by cognitive neuroscience literature , ,  and done in [1]}, as opposed to the over 20 minutes in [2]}, in order to avoid the subjects becoming inattentive and their related neural responses not containing visual stimuli content;

To pool data from multiple subjects, as done in [1]} and opposed to the per-subject analysis proposed in [2]}, in order to avoid models to learn spurious specific-subject dynamics rather than a shared representation pertaining the shown stimuli.
